    Discovery of Pyrazolo[1,5,4-de]quinoxalin-2(3H)-one Derivatives as Highly Potent and Selective PARP1 Inhibitors. (PubMed, J Med Chem)
    30 achieved tumor regression in the BRCA1-mutated MDA-MB-436 xenograft model and showed synergistic efficacy in combination with carboplatin in the SUM149PT xenograft model. In the rat hematological toxicity study, 30 exhibited minimal impact on hematological parameters at 25 mg/kg, while AZD5305 at 1 mg/kg caused 56.5% reduction of reticulocyte. Taken together, we discovered compound 30 with a therapeutic index superior to that of PARP1 inhibitors AZD5305 and AZD9574 in the preclinical setting.

    H3K27M diffuse midline glioma is homologous recombination defective and sensitized to radiotherapy and NK cell-mediated antitumor immunity by PARP inhibition. (PubMed, bioRxiv)
    We also show that the novel brain penetrant, PARP1-selective inhibitor AZD9574 compares favorably to olaparib when combined with RT, prolonging survival in a syngeneic orthotopic model of H3K27M DMG. This study highlights the ability of PARP1 inhibition to radiosensitize and induce an NK cell-mediated antitumor immunity in H3K27M DMG and supports future clinical investigation.

    Preclinical Characterization of AZD9574, a Blood-Brain Barrier Penetrant Inhibitor of PARP1. (PubMed, Clin Cancer Res)
    The combination of three key features - PARP1 selectivity, PARP1 trapping profile, and high CNS penetration in a single molecule, supports the development of AZD9574 as the best-in-class PARP inhibitor for the treatment of primary and secondary brain tumors. As documented by in vitro and in vivo studies, AZD9574 shows robust anti-cancer efficacy both as a single agent as well as in combination with TMZ. AZD9574 is currently in a phase I trial (NCT05417594).

    AZD9574 is a novel, brain penetrant PARP-1 selective inhibitor with activity in an intracranial xenograft model of triple negative breast carcinoma with homologous recombination repair deficiency (SNO 2022)
    Treatment of animals with established intracranial lesions showed sustained tumour growth suppression resulting in a significantly extended survival of tumour-bearing mice. Collectively, we believe that our data support the development of AZD9574 as a potential therapy for patients with HRD+ breast cancer whose disease has spread to the brain.This abstract was previously presented at AACR 2022 (Hamerlik et al, AACR 2022, Abs #3880)

    AZD9574 is a novel, brain penetrant PARP-1 selective inhibitor with activity in an orthotopic, intracranial xenograft model with aberrant DNA repair (AACR 2022)
    Treatment of animals with established intracranial lesions using a dose of 3 mg/kg AZD9574 showed sustained tumour growth suppression resulting in a significantly extended survival of tumour-bearing mice. Collectively, we believe that our data support the development of AZD9574 as a potential therapy for patients with HRD+ breast cancer whose disease has spread to the brain.
